Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting a label tube on a bottle or the like.

[0002]

2. Description of the Related Art In recent years, instead of directly printing or labeling bottles made of glass, resin, etc., in recent years, trademarks,
A method of covering a label tube on which a product name, a pattern, or the like is printed, and fixing the label tube to the bottle by a method such as heat shrink is generally used. Alternatively, a method in which a film on which a trademark, a product name, a pattern, or the like is printed is fixed by an adhesive such as glue.

[0003]

However, the method using heat shrink requires a heating furnace, not only lengthening the line but also often requiring fine adjustment of the finish. In addition, when the cross-sectional shape is a non-circular shape such as a square, and it is required that the shape of the bottle and the position of the printing pattern of the label tube have a specific relationship, the process from the time when the label tube is covered until the heat treatment is completed. During this time, the bottle must be handled with great care so as not to cause a displacement of the label tube. Furthermore, conventionally, since it was a method of covering the label tube with a sufficient margin compared to the cross section of the bottle and fixing it to the bottle by heat shrink,
If the thickness of the label tube is insufficient during the period from the mounting of the label tube to the heating, there is a problem that the label tube is bent by its own weight, and the cost reduction is limited. On the other hand, those using an adhesive have a problem in that the mixture of different components hinders regeneration and reuse. An object of the present invention is to provide an apparatus for performing a label tube mounting operation that does not have such a problem.

[0004]

The label tube fitting device of the present invention includes an insertion guide inserted into a label tube of a predetermined size, and a label tube expanded by the insertion guide inserted into the label tube. A drive device for inserting the bottle, a holding device for holding the position of the label tube fitted in a predetermined position of the bottle, and a drive device for retracting the insertion guide until the engagement between the insertion guide and the label tube are released. Features. When the bottle is inserted, the label tube is slightly narrower than the bottle diameter and is expanded by the insertion guide, and a tube holder that presses and fixes the label tube on the insertion guide is arranged so that the label tube does not move when the bottle is inserted. It is good to set up. This fitting device can be advantageously used especially when a so-called stretch film that can be reversibly stretched by force is used as a label tube,
Even when a thin heat shrink film label tube is used, there is no problem as in the conventional apparatus.

The above configuration will be described more specifically.
Referring to FIG. 1 (a), the label tube fitting device includes 1
It has a pair of insertion guides 1 and is inserted into the label tube 2 with the spacing between the insertion guides 1 narrowed. Next, an actuator or cam drive (not shown)
The tube 2 is expanded by driving the insertion guide 1 in a direction indicated by an arrow in the figure so as to have a slightly smaller interval than the outer diameter of the bottle 3 by an appropriate driving device. FIG.
Then, the bottle 3 is inserted into the expanded label tube 2. At this time, the label tube 2 is pushed by the bottle 3 and further expanded together with the insertion guide 1. At this time, the tube presser 4 is used to prevent the label tube 2 from being pushed out of the insertion guide 1.
Secures the lower part of the label tube 2 to the insertion guide 1.
As a result, the lower part of the label tube 2 is fixed, and the upper part of the label tube 2 is fitted to the bottle while being stretched and stretched. Referring to FIG. 3 (c), when the insertion of the bottle 3 is completed and the label tube reaches a predetermined position of the bottle, another tube retainer 5 holds the label tube, preferably at the upper portion thereof, onto the bottle. To prevent the tube position from shifting when the insertion guide 1 is retracted. Referring to FIG. 2D, the tube presser 4 retreats as indicated by an arrow, disengages the connection with the insertion guide 1, and the insertion guide 1 descends until the engagement with the label tube 2 is released. During this time, the tube holder 5 holds the position of the label tube.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 2, the label tube fitting apparatus of the present invention has a web-like folded label tube which is cut one by one and supplied to a main turret A. Turret B, which is a label tube supply device to be expanded, the supplied label tube is expanded by an air piece or the like, an insertion guide is inserted, and the extended portion is stretched and expanded by the insertion guide [(a) → (d) ], By inserting a bottle or the like in the expanded state and pulling out the insertion guide, the label tube is restored and contracted and fitted to the bottle or the like with the force of contraction [(e) → (h)], conveyor A main turret A comprising an intake section for taking in a bottle from a supply device such as a discharge section for sending out a bottle fitted with a label tube;
It comprises a supply starwheel C as a bottle supply device and a discharge starwheel D as a discharge device.

More specifically, the fitting of the label tube in the main turret A is performed as follows. Referring to FIG. 3A, in the extension portion, the label tube 11 supplied from the soccer turret B is suction-held by the pair of air pieces 12, 13, and is opened by opening the air piece as shown by the arrow. [(B) →
(B)]. Next, the insertion guide 14 is inserted (c),
Push and expand to a size sufficient to insert the bottle 15 (d). Referring to FIGS. 8B and 8C, the pilot 17 moves the bottle 15 supplied onto the bottle table 16 in the fully expanded label tube as shown by the arrow in the label tube extending step. Drop to the bottle 15
[(E)], the bottle 15 is raised by the bottle table 16 as shown by the arrow, and the label tube 1
[(F)]. At this time, the upper air piece 12 retracts as shown by the arrow. Next, when the insertion of the bottle is completed, the upper air piece 12 advances as shown by the arrow to hold the label tube 11, while the lower air piece 13 opens as shown by the arrow to open the insertion guide 14 [(g. )], The insertion guide 14 descends and separates from the label tube [(h)]. Referring to FIG. 2D, the bottle 15 fitted with the label tube 11 is lowered with the head fixed by the pilot 17 [(R)], and then the pilot rises to complete a series of processes. [(Nu)].
The bottle is discharged, a new label tube is supplied to the air pieces 12 and 13, and the process returns to (A).

During the above operation sequence, it goes without saying that the entry of the bottle 15 into the expanded label tube 11 may be performed by raising the bottle or by lowering the label tube 11. In addition, the opening diameter of the label tube 11 in the state of (f) is smaller than the diameter of the bottle 15, and the bottle 15 pushes the label tube and the air piece to enter, so that the amount of stretching is excessive. In addition to preventing irreversible stretching from occurring, the label tube 11 can be fitted into the bottle from the upper end side, so that the label tube can be loosened during fitting by a kind of ironing effect. This is because there is no risk of being stretched and causing wrinkles. But,
Depending on the conditions, it is also possible to set conditions so as to be wider than the bottle diameter.

[0009]

In the apparatus shown in FIG. 2, the soccer 21 of the soccer turret B is an odd-numbered label soccer and the 22 is an even-numbered soccer. Thus, every other label tube to be supplied to the air pieces 12 and 13 is provided. By doing so, the rotation speed of the main turret A can be increased. According to such a configuration, the label tube supplied by being folded into a web shape has an odd-side feed 2.
3 and an even-numbered side feed 24, which are cut one by one by a label cutter (not shown) at 25 positions and supplied to each soccer. In order to prevent interference at the receiving position of the label tube, the cam so that the odd-numbered soccer retreats as shown by the solid line and the even-numbered soccer retreats avoiding the other trajectory, as indicated by the dotted line. Driven by When the label tube is passed to the air piece by using such a soccer that can be moved in the radial direction, the tip of the label tube hits the air piece, and the action of passing the label tube between the air tubes becomes uncertain. The label tube can be inserted between the air pieces by driving the soccer radially inward from the outside so that there is no gap.

In FIG. 1, the tube holders 4, 5 are
Although provided as independent mechanisms, FIGS. 2 and 3 show a structure in which an air piece for holding the label tube is also used. Therefore, the air piece 1
2 and 13 are configured so that the upper and lower sides can be opened and closed independently. Referring to FIG. 4, the upper air piece 12 is pivotally mounted on the main turret by a shaft 31 and is biased in a direction to close each other by springs 32 and 32 ′ (only one spring is shown in FIG. 4A). Has been.). The driven cam follower 34 provided on the air piece 12 is driven by the driven cam 33 by the spring 32.
The opening and closing of the air piece 12 is controlled. The driven cam 33 is pressed by the main cam 35 by a spring 37, and controls opening and closing of the air piece 12 by moving forward and backward. 36 is a cam follower provided on the driven cam 33. As seen in FIG. 2B, the same drive mechanism is also provided on the lower air piece 13, and the upper and lower air pieces are separately opened and closed by the difference in the main cam shape. It acts to pull open, hold down and open the label tube.

In FIG. 1D, the distance 1 from the lower end of the label to the bottom of the bottle varies depending on the design of the bottle and the label, and must be freely adjustable. This adjustment is performed by providing the upper and lower adjusting devices of the soccer turret and the main turret, and adjusting the heights of the soccer players 21 and 22 and the air pieces 12 and 13 with respect to the bottle table 16. Needless to say, there can be only one label feed for the soccer turret, depending on the required performance. However, also at this time, there is an effect that the label tube is inserted between the air pieces by the movement of soccer.
